Results for "CO2 flooding"
How does a fixed CO2 flooding fire-extinguishing system work?
A fixed CO2 system extinguishes a fire in a protected space such as the engine room by flooding it with carbon dioxide, which displaces the oxygen the fire needs — after everyone is evacuated.
Shipboard OperationsWhat are the classes of fire and which extinguishers are used on ships?
Fires are grouped into classes by what is burning, and each class needs the right extinguishing agent — using the wrong one can be ineffective or dangerous.
